• AD5116: lifetime at auto-save mode

    Hi, when I am using AD5116 for a project, I am curious about the lifetime of AD5116 at auto-save mode. Please refer to the following information highlighted from datasheet.

    If I power-on the AD5116 at auto-save mode and there is no any PD/PU inputs…

  • AD5116

    Hi,

    I have a5 fault in the AD116.

    The Auto Save Enable (ASE) dose not woks constantly.
    I realized it's depends on the fulling time of the PD/PU.

    Is the Auto Save Enable requires a minimum value for the fulling time?
    It dose not mentioned on the DataSheet…

  • AD5116

    Hi,

    I am using the AD5116 rheostat in my application and I have a problem related to parameter shift over temperature that is greater then the typical values given in the DS.

    I started with a room temperature (25C) and set W to be 50%, I raised the temperature…

  • Default setting of AD5116

    Hi

    I'm a DFAE in Japan. I get a question by our customer regarding AD5116. Where is the wiper when the AD5116 ships? Is it shorted to A or B? Or is it somewhere between A and B?

    Regards,

  • Two AD5116 + One SSM2306

    Hi,

    I am planning to use ADI push button in my volume control design.

    I will use SSM2306 (Stereo Audio Amplifier) in this project, and I am wondering if I can use 2 AD5116 to do the volume control? Each AD5116 will be connected with Left or Right channel…

  • AD5116: Pull-up / Pull-down resistors

    Regarding the pull-up/pull down resistors for the PU and PD input, there is a
    discrepancy in the datasheet as in the picture on
    pageone of the datasheet, you will see a pull down resistor on the PU/PD input.
    Well, on page 13 you will find a desciption…

  • Hi, i  am new to audio analog engineer. I have planned to design headphone volume control circuit using AD5116. Is it fine to use this digital pot for this application?

    Hi, i  am new to audio analog engineer. I have planned to design headphone volume control circuit using AD5116. Is it fine to use this digital pot for this application? Anybody have reference design for headphone volume control circuit?

  • RE: Digital pot with SigmaDSP?

    Hi SKfir and Coleman,

    The AD5116 does not need ext caps as include an internal debounce circuitry.

  • RE: possible to use AD5228 as stereo volume control?

    Hi cklooi,

    You can do that. It should not be a problem.

    what do you mean by logic output? internally there is a pull-up resistor.. but I dont remember the value.

    BTW.. just in case, the AD5116 could offer similar functionality with embedded memory…

  • RE: AD5245 for Volume control

    Hi,

    The issue here is that the AD5245's attenuation is not really suited to audio applications. Figure 19 in the datasheet (attached below) shows at zero code that the gain is approximately -45dB.  There is also no shutdown feature either to eliminate…
